I'm thinking the very system of monetary exchange is going to change so fundamentally that I'm not sure if it will truely matter if its metals/crpto or otherwise when you factor in the WORLD.
A very very small faction of the worlds population considers things like those.
How do you change the system fundamentally that EXCLUDES incentive of greed and overall mentality of "chasing money"?
But of course before that eventually happens, I believe we all will go through a "transitional" economic based economy.
